Description

Sept. 6. 1952 A. s.'cARLsoN BOUNDARY MARKER Filed Oct. 20, 1945 INVENTOR. flxel S. Oar'lson :Icy-.2.
fltornef and assuming the parts in the position shown in,
full line in Fig. 3, the latching element is fully nested on its seat, and one edge of the hole engages the noteh 31 to hold the shaft 35 in the position shown. It will be noted that the top of V the head 38 of the shaft is at this time flush with the topof the stone 30. When it is desired to elevate the shaft for the purpose of more definitely marking the boundary, it is merely a well therein and a recess 'of predetermined shape at the top thereof into which said well opens, a shaft disposed within said well in such a manner that there is a snug sliding fit between said shaft and the upper portion of said well, said shaft being adapted to be moved axially of said well and having laterally extending vertically spaced notches thereon, and a latching element of the same shape as said recess having a rimdefim'ng an elongated hole therein movable into and out of engagement with said recess, said shaft being disposed through said hole, and the dimensions of said notches, said shaft and said rim being such that said rim is movable into and out of engagement with each'of said notches when said latching element is moved away from necessary to grasp the head 38 and pull up on the shaft 35. This will temporarily cause the latching element 32 to be lifted with' the shait, but a slight lateral manipulation of the latching element as shown by arrows in Fig. 3 will release it from engagement with the noteh 31 and cause it to drop by gravity along the shaft and to at least partly` enter its seat or recess 33.2 As the shaft is lifted to bring the lower noteh 35 just above the topuof sleeve 39, the latching element will, by gravity, move into full nesting 'position within its seat to dispose its aperture in eccentric relation with the shaft and with one edge lying in the noteh 36, thus holding the shaft inits elevated position. When it is desired to lower the shaft, it is merely necessary to' raise 'it slightly and manipulate the latching element laterally to release it fromengagement 'With the noteh 36 whereupon the shaft` may be lowered until seated position in said recess.
3. A boundary marker including a stone having a Well therein and a recess of predetermined shape at the top thereof into which said well opens, a shaft disposed within said well' in such manner that there is a snug sliding fit between said shaft and the upper portion of saidwell, said shaft being adapted to be moved axially of said well and having laterally extending vere tically spaced notches ,thereon, and a latching element having an elongated opening therein movable into and out of seated engagement With its noteh 31 comes into alignment with the hole in bottom of the latching element whereupon the parts will reassume, their latching, ,relation shown in full lines of.1='ig. 3. A rim or flangevfiz is provided at the bottom of the shaft 35 to prevent its completeremoval from the stone;
It will ;be seen that I have-provided a simple, inexpensivabut highly eflicient marker, which may be readily operated and simply moved from the `inoperative to the operative position. r It will be appreciated that this will save considerable time andinconvenience in locating boundary lines and at the same timewhen not needed can be dropped out of sight.
I claim: v
1. A boundary marker including a stone having a well therein and a recess at the top thereof having downwardly and inwardly sloping walls into which said well opens, a shaft' disposed within said well, the dimensions of said shaft being such that there is a snug sliding fit between said shaft'and the upper portion of said well, said shaft being adapted to be moved axially of said well, said shat having laterally extending vertically spaced notches, and a disk-shaped latching element in engagement with and supported by said recess having an elongated opening therein, said latching element being movable away from said recess, said shaft being disposed within said opening, a portion of said latching element adjacent said opening being received by one of said notches when said latching element is fully seated in said recess, the dimensions -of said opening in; said latching element,` said notches and said latching element being such that said portion of said latching element can be moved'out of said one of said notches when said latching element is moved away from said recess. v V
, 2. A boundary marker including a stone having said recess, said shaft being disposed within said opening, a portion of said latching element adjacentsaid opening' being received by one of said notches when said latching element is fully seated in said recess, said recess'having inwardly and downwardly sloping wa1lsand said latching element having complementary sloping surfacesso 'that said latching element will tend to seat in said' recess upon movement of said latching element into said recess i 4. A boundary marker including a stonehaving a well therein and a recess of, predetermined shape at the top thereof into which said well opens, a shaft disposed within said well in such manner that there is a snug' sli'ding fit between said shaft and the upper portion ,of said well, said shaft being adapted to be moved axially of said well and having laterally extendingvertically spaced notches thereon, and a latching element of the same shape as said recess and having an elongated opening therein movable into and' out of seated engagement with said recess, said shaft being disposed within said open ing, a portion ofsaid latching element adjacent said opening being received by one of said notches, when said latching element is fully seated in said recess, the dimensions of said latching element said opening and said portion being such that said latching elementmay be moved .lateral to the axis of said shaft when said element is not fully seated in said recess so as to move said portion out of said one of said notches.
